Determining malfunctioning part

If the vehicle identification cannot be done because the M-MDS vehicle identification is performed using the CAN system between the PCM and DLC-2, determine the malfunctioning part in the HS-CAN.
Select HS-CAN or MS-CAN from the unit outputting the DTCs because there are HS-CAN and MS-CAN in the CAN-lines. Select HS-CAN or MS-CAN from DTC content because the HS-CAN and MS-CAN are connected to the instrument cluster.
